Let me just express how scary it was putting a drill to my brand new cabinets! Luckily everything went smoothly and we don't have any stray holes. I got these handy templates from home depot so there was no measuring required for the knobs, and for the pulls I only had to measure the center of the drawer and the template did the rest.
Although I actually enjoyed doing this, I think it may have been worth it to just pay Ryan Homes to do it. Depending on the quality and options (I'm not sure what kind of selection RH offers), it might actually be equal or cheaper to have them do it. For my house (the Courtland), RH charged $195 and I believe that was for the kitchen plus both upstairs bathrooms. The total cost for me to do it myself for just the kitchen was $85. I got two ten-packs of the knobs for $20.00 each and 10 pulls at $2.58 each, plus the cost of the templates ($7.47) and tax. It is probably at least double that if you included the two bathrooms as well plus the anxiety caused by drilling holes into your cabinets.
Does anyone know what kind of options RH offers for cabinets hardware? Do they have a good selection?
